“…The relative position of the two P(III)-functions was confirmed by 31 P NMR spectral data and quantum chemical calculations [65,[84][85][86][87][88]. It is noteworthy, that the platinum complex of the 3-diphenylphosphino-1-phenyl-1,2,3,6-tetrahidrophosphinine (36*) was also prepared in an optically active form [65].…”

The use of the microwave (MW) Keywords organophosphorus chemistry, green chemistry, microwave, resolution, platinum complexes, dronic acids/dronates IntroductionIn this minireview, our recent results in environmentallyfriendly ("green") chemistry have been summarized. In the first sub-chapter the usefulness of the microwave technique is shown in organophosphorus chemistry. The second sub-chapter summarizes our results on the resolution of cyclic phosphine oxides, as precursors for P-ligands and on the synthesis of platinum complexes as potential catalysts. Catalysts are of utmost importance from the point of view of green chemistry. The last sub-chapter comprises our experiences on the optimization of the synthesis of dronic acid derivatives that are important drugs against bone diseases.

“…It is worthy to mention that the cis chelate structure of complex 6 is of novelty. In some respects, analogous platinum complexes incorporating the 3-diphenylphosphino-1-phenyl-1,2,3,6-tetrahydrophsophinine or the 3-diphenylphosphino-1-phenyl-1,2,3,4,5,6-hexahydrophosphinine bidentate P-ligands were described by the authors in previous articles [25,26]. The stereostructures of the Pt(II) complex 6 and its bidentate P-ligand 3 were evaluated by B3LYP/6-31G * calculations, and LANL2DZ calculations for Pt.…”

The members of a logically built P-heterocyclic family are discussed systematically to show a dynamically developing discipline of organophosphorus chemistry. Dichlorocyclopropanation of 2,5-dihydro-1H-phosphole oxides led to 3-phosphabicyclo[3.1.0]hexane 3-oxides that were useful intermediates for the synthesis of ring expanded products, such as 1,2-dihydrophosphinine oxides and 3-alkoxy-1,2,3,6-tetrahydrophosphinine oxides. Catalytic hydrogenation of 1,2-dihydrophosphinine oxides gave 1,2,3,4,5,6-hexahydrophosphinine oxides. Selective reduction of the , -doublebond of 1,2-dihydrophosphinine oxides via hydroboration led to 1,2,3,6-tetrahydrophosphinine oxides. Michael addition of >P(O)H species to the electron-poor double-bond of 1,2-dihydrophosphinine oxides afforded 1,2,3,6-tetrahydrophosphinine oxides with exocyclic P-function in position 3. Hydrogenation of these P-heterocycles led to the corresponding hexahydrophosphinine oxides. Stereostructure and conformation of the tetra-and hexahydrophosphinine oxides were elucidated by stereospecific NMR couplings and/or quantum chemical calculations. After deoxygenation, some of the above P-heterocycles were suitable P-ligands in transition metal complexes. The 1,2-dihydrophosphinine oxides were also useful in the synthesis of aromatic phosphinines, phosphepine derivatives and phosphabicyclo[2.2.2]octene oxides, as well as hetrocyclic -oxophosphoranes.
